      It should not restart user-initiated index builds.

      Scenario:
      1) User starts building a unique index on {a:1} on the current primary, node A.
      2) Node A dies suddenly (kill -9 or power failure, etc) and node B becomes the new primary.
      3) Node A restarts and the IndexRebuilder restarts building of the index.

      At this point, node A now has an index that does not exist on the primary and never will. This would be less of a problem for a non-unique index, but because this is unique, an insert can now succeed on the primary but fail on node A, breaking replication.

      I think the right solution is to only rebuild indexes where we would not call logOp on completion.
